Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]	1. Organization Western Refining Logistics, LP ("WNRL" or the "Partnership"), "we," "us," and "our" refer to Western Refining Logistics, LP, and, unless the context otherwise requires, our subsidiaries. References to “Western” refer to Western Refining, Inc. WNRL is a Delaware limited partnership formed in July 2013, by Western Refining Logistics GP, LLC ("WRGP" or the "General Partner"), our general partner. WRGP is indirectly 100% owned by Western and holds all of the non-economic general partner interests in WNRL. As of March 31, 2017, Western owned 52.5% of the limited partner interest in WNRL and public unitholders held the remaining 47.5%. See Note 10, Equity, for additional information. WNRL is principally a fee-based growth-oriented partnership that was formed to own, operate, develop and acquire logistics and related assets and businesses including terminals, storage tanks, pipelines and other logistics assets related to the terminalling, transportation, storage and distribution of crude oil and refined products. WNRL's businesses include 705 miles of pipelines, approximately 12.4 million barrels of active storage capacity, distribution of wholesale petroleum products and crude oil and asphalt trucking. On March 2, 2017, the requirements for the conversion of all subordinated units into common units were satisfied under the partnership agreement. As a result, the 22,811,000 subordinated units held by Western converted into common units on a one-for-one basis and thereafter participated on terms equal with all other common units in distributions of available cash. See Note 10, Equity, for additional information. On November 16, 2016, Western entered into an Agreement and Plan of Merger (the “Tesoro Merger Agreement”) with Tesoro Corporation, a Delaware corporation (“Tesoro”), Tahoe Merger Sub 1, Inc., a Delaware corporation and wholly-owned subsidiary of Tesoro (“Merger Sub 1”), and Tahoe Merger Sub 2, LLC, a Delaware limited liability company and wholly-owned subsidiary of Tesoro ("Merger Sub 2"), pursuant to which Merger Sub 1 will merge with and into Western (the “First Tesoro Merger,” and, if a second merger election as discussed below is not made, the “Tesoro Merger”), with Western surviving the First Tesoro Merger as a wholly-owned subsidiary of Tesoro. The Tesoro Merger Agreement permits either Western or Tesoro, for tax considerations, to require the surviving corporation of the First Tesoro Merger be merged with and into Merger Sub 2 immediately following the effective time of the First Tesoro Merger, with Merger Sub 2 being the surviving company from the second merger (the “Second Tesoro Merger,” and if the second merger election is made, collectively with the First Tesoro Merger, the “Tesoro Merger”). The Tesoro Merger is subject to the satisfaction or waiver of the closing conditions provided in the Tesoro Merger Agreement. We will continue as a public entity and our debt will remain outstanding following the completion of the Tesoro Merger. On September 15, 2016, we acquired certain terminalling, transportation and storage assets from a wholly-owned subsidiary of Western consisting of the Cottage Grove tank farm and certain terminals, storage assets, pipelines and other logistics assets located at Western's St. Paul Park refinery ("St. Paul Park Logistics Assets"). The St. Paul Park Logistics Assets primarily receive, store and distribute crude oil, feedstock and refined products associated with Western's St. Paul Park refinery. We acquired the St. Paul Park Logistics Assets from Western in exchange for $195 million in cash and 628,224 common units representing limited partner interests in WNRL. We refer to this transaction as the "St. Paul Park Logistics Transaction." This transaction was between entities under common control. See Note 3, Acquisitions of Common Control Assets, for additional information. The financial statements presented in this Quarterly Report on Form 10-Q have been retrospectively adjusted to include the combined financial results of the St. Paul Park Logistics Assets prior to September 15, 2016. The historical operations of the St. Paul Park Logistics Assets prior to the St. Paul Park Logistics Transaction generally recorded operating costs and other expenses associated with storage and terminalling services and recorded no revenue. For periods subsequent to the St. Paul Park Logistics Transaction, the results of operations for the St. Paul Park Logistics Assets reflect revenues based on contractual rates set forth in our commercial agreements with Western. See Note 16, Related Party Transactions, for additional information. Our operations include two reportable segments: the logistics segment and the wholesale segment. See Note 4, Segment Information, for further discussion of our reportable segments.
